For Andy, I don't think it's rust, I think it's more confidence. He's playing tennis, but he's reacting, he's not knowing a chess piece ahead what is going to happen.

FD is a little too keen to take the first point as he goes for glory with a Hollywood forehand.

15-0.

Murray then should have made an easy forehand but finds the netting.

15-15.

30-15 and Murray mutters to himself. Coach Jamie Delgado looks concerned.

30-30.

Less concern.

...head to one of the sun-drenched eating areas. It’s packed here today, not that you’d know it from this photo. The issue is not only the sun, but the heat of the seats. That’s why there are empty gaps in stadiums too - it’s too painful to sit down.

This first set is getting away from Cameron Norrie.

Dusan Lajovic brings the break streak to an end by holding serve to make it 4-2, but then sees off Norrie again to give himself a shot at serving for the opener.

Norrie's been broken three times in the first set.

Third seed Juan Martin del Potro has taken the first set comfortably against American Denis Kudla over on Louis Armstrong Stadium. The Argentine has not faced any break points in this match so far.

Murray does a double. Not great timing.

Broken. In more ways than one.

Verdasco presses down the power bar with a double hander.

Break point for 'Dasco.

Verdasco flicks through his Tennis Magic Circle book and pulls out a neat trick - a deft lob over Murray. Lovely.

15-15.

30-15.

30-30.

Murray at the net employs soft hands to dink an angled volley winner.

But Verdasco bites back with a 90mph forehand.

Ferocious.

Deuce.

"Are you going to call it? Are you call it?"

Verdasco asks the umpire during that contentious shot in deuce. No, Fernando, he's not. And the review system shows why.

Both players out of challenges.

Deuce, as Murray's return is called in.

The Scot then finds the net.

The 34-year-old finally seals after Murray finds the net again.

Muzza had his opportunities there.

A stunning second serve is followed by a terrible double fault followed by an ace.

A minute in the life of Fernando Verdasco.

Advantage 'Dasco.

There's an interesting match unfolding on Court 17, where ninth seed Dominic Thiem has fought back from 2-1 down to go into a fifth set against American Steve Johnson.

Somebody hold serve...

Another break in the match involving the British number two out on Court 10. That's three on the bounce.

This one goes in the favour of Dusan Lajovic. Can Cameron Norrie repeat the trick?

Saved with an ace.

Just. The computer is content.

Deuce.

0-30.

Then Murray goes wide with a forehand - that could have been three break/set points.

15-30.

30-30 thanks to a 70mph on his backhand.

Verdacso then goes long.

Set point.

That's our first Paul Weller moment from Andy Murray... 'Come on, let's go." Ask your indie mod mum or dad.

That shout is when you know Murray has eked himself out of a tight spot.

Is that the fella from American Pie? Also is Leonardo DiCaprio's funny mate from Wolf of Wall Street also inside Arthur Ashe Stadium?

It's like a who's who of people who possibly might be famous.

That didn't take long. Cameron Norrie hits back immediately with a break of his own - 15 minutes gone, a break a piece and we're back on serve.

Time for a quick Cameron Norrie history lesson...

The left-hander was born in South Africa to a Scottish father and a Welsh mother, moved to New Zealand when he was a child, but switched allegiances to Great Britain when he was 16, partly due to a lack of funding from Tennis NZ, briefly living in London before moving to Texas for university.

Got it?

Deuce. Murray goes long.

"C'mon!!!" shouts Murray again as wins the first point.

Verdasco then says words that might have been rude. They might not have been.

And goes on to lose the game - he had Murray under pressure there.
